The belongings of nearly 25 foreign exchange students at St. Bernard's Catholic School were stolen over the weekend after thieves opened boxes in the school's dormitory and rifled through items, officials said on Tuesday.

The thieves broke into the Eureka school, located at 222 Dollison St., late Saturday night or early Sunday morning and then again on Sunday night or early Monday morning, St. Bernard's President David Sharp said. School officials aren't completely sure, but believe the burglars broke in through a window.

"It's likely someone had to have some knowledge of the facility to make it happen," Sharp said.

Staff don't know everything the thieves took, but were able to confirm a flat screen television, Nintendo, Xbox, motor scooter and van are gone. They are in the process of notifying the students to learn exactly what was taken.

The students, who live in the residence hall during the school year, packed up their belongings at the end of the term that they wanted kept in storage while home in China or South Korea during the summer, the school's executive assistant Lynn Pretzel said.

With the school year just ending, the boxes were still in the hallways and hadn't been moved into a storage unit.

"I feel bad for the students whose personal items were gone through," Sharp said. "Some of it was stolen. There's insurance to recover the students' belongings but that's really unfortunate for a student to leave their stuff behind and for somebody to come along and take advantage of that and take their stuff."

The Eureka Police Department has no suspects at this time, but believes up to three people were involved, Chief Murl Harpham said. School officials released surveillance video that shows two people entering the building.

"They were in there a long time, apparently, and they knew where the key was hidden for the van," Harpham said. "It's suspicious because they knew where the key to the van was. They knew where the stuff was, and they took what they wanted."
